Info

• Formatted text (Space delimited) (*.txt). This format exports in Windows ANSI text files. The delimiter between data columns is a space " ". • Text (MS-DOS) (*.txt). This format exports in OEM ASCII text files. The delimiter between data columns is the tabulator "\t". This format is useful when exporting files that need to be read by another system using the standard ASCII character set. • CSV (Comma delimited) (*.txt). This format exports in Windows ANSI text files. CSV stands for comma-separated-values. The delimiter between data columns is determined by the Windows Regional Settings of the PC exporting the data. Please note that the character of the List Separator is used and not (as maybe expected) the Decimal Symbol. • Excel® Export (*.xls). This format exports in Microsoft® Excel® file format. The format is known as BIFF2, which goes back to Excel version 2.1 for Microsoft® Windows®. Using this older format ensures that newer versions Excel can open the file. Remember that because Excel only supports up to 65.000 rows, this is the maximum number of rows exported. • XML generates files in .xml format, readable by an Internet browser. Include row numbers The property Include row numbers is used to determine whether or not a sequential numbering of the exported data should be included. By default this property is set to No/Off. Include header Additional header information is added to the exported files if the Include header is Yes/On. For each exported file the traverse position and the project name is included in the header. Note that if this is not selected ASCII-export does not include any header information other than the column names. Export measurements Properties By ticking this option, the configuration properties will be exported in a separate file. This file includes all the properties, processor, group, channels, and optics or can be customised by the user. Please, refer to chapter 5 Output properties about how to customize the properties export. 5.9.2 Filter The measurement properties file is exported in the same folder as all the other exported files. The name of the exported file is constructed as: the {Base file name}.all.xml and is in xml format. . The properties Filter displays (read only) the format of the exported file as chosen in the Export Data file dialog box. 5-52 BSA Flow Software: Project explorer objects
5.9.3 Selected columns 5.9.4 Binary Export Structure of Binary File The property Selected columns determine which data is included in the export, and allows the user to arrange columns in a different order. It will bring up the dialog shown in Figure 5-45: Figure 5-45 Selecting the data to be exported after a moment object The actual data available depend on the parent-object of the export-object itself. In the example in Figure 5-45, the parent object was Moments from a 1-Dimensional LDA. A “Zero”-column is available to fill in blank columns in the exported data. This will facilitate importing data into programs requiring a specific format. For example a blank could be filled in if the receiving program requires coordinates X, Y and Z, and you have only X, and Y available. The Export object will export data with the format defined under Tools - Options - Data formats. The BSA Flow Software offers binary export of data. The binary format is more compact than the ASCII export formats. The export can be initiated either from the Export Object or from the List export command. The overall structure of the binary file is displayed in Figure 5-46. The first part of the binary file contains a file header of 518 bytes, please see Table 1. This describes the contents and origin of the binary file. Following the file header a number of data blocks each representing a data column is placed. Each of these blocks begins with a data header of 154 bytes. This header describes the format and size of the data. BSA Flow Software: Project explorer objects 5-53
